Viewing on a vertical browser is awful... there's two columns - one on the left-hand side about 60% of the view port which contains every little piece of content and the 40% remainder on the right-hand side is completely blank white space.

I've got an adblocker enabled so perhaps the right-hand side is supposed to be littered with ads? Either way the readability factor has been thrown out the window, thankfully FireFox's reader view comes in handy again.
